Hmmm... to answer my own question, it appears that PS3 does not have a
PCI or PCIe.   It does have USB though:

------------------------------------------
USB

PS3 equips industry standard USB EHCI host controller and its
companion OHCI host controllers. Although most USB host controllers
are PCI devices, PS3 USB host controller exists in the companion chip.
The PCI probe routines of Linux are modified so that PS3 USB host
controller can imitate PCI device. After initialization, all
operational registers of USB host controllers are directly accessed by
PPE, so no modification to original Linux USB host controller driver
is needed. PS3 has internal high speed USB hub. The USB ports of PS3
front panel is connected to the hub, not to USB host controller
directly. This PCI probe modification would be change later to get
better device driver maintainer acceptance.
